[v6,0/3] Add support for RZ/G2L VSPD

  The RZ/G2L VSPD provides a single VSPD instance. It has the following
sub modules MAU, CTU, RPF, DPR, LUT, BRS, WPF and LIF.

The VSPD block on RZ/G2L does not have a version register, so added a
new compatible string "renesas,rzg2l-vsp2" with a data pointer containing
the info structure. Also the reset line is shared with the DU module.

v5->v6:
 * Rebased to media_staging and updated commit header
 * Removed LCDC reference clock description from bindings
 * Changed the clock name from du.0->aclk from bindings
 * Added Rb tag from Laurent for reset patch
 * Added forward declaration for struct reset_control
 * Updated vsp1_device_get() with changes suggested by Laurent
 * Updated error message for reset_control_get form ctrl->control.
 * Removed the extra tab from rzg2l_vsp2_device_info
 * Changed the function vsp1_lookup->vsp1_lookup_info and
   all info match related code moved here.
 * Add VI6_IP_VERSION_VSP and VI6_IP_VERSION_VSP_SW macros to
   distinguish HW & SW IP_VSP_Version.
 * Used 0x80 for RZG2L VSPD model and SoC identification
 * Updated Switch() for LIF0 buffer attribute handling.
v4->v5:
 * Fixed typo VI6_IP_VERSION_MODEL_MASK->VI6_IP_VERSION_MASK
 * To be consistent with other SoC's, introduced VI6_IP_VERSION_SOC_G2L
   for SoC identification for RZ/G2L SoC's.
v3->v4:
 * Restored error check for pm_runtime_resume_and_get and calls
   assert() in case of failure.
 * Added Rb tag from Geert
 * Add switch() for LIF0 buffer attribute handling for RZ/G2L and V3M SoC's
v2->v3:
 * Added Rb tags from Krzysztof and Philipp
 * If reset_control_deassert() failed, return ret directly.
 * Fixed version comparison in vsp1_lookup()
v1->v2:
 * Used reference counted reset handle to perform deassert/assert
 * Changed the compatible from vsp2-rzg2l->rzg2l-vsp2
 * Added standalone device info for rzg2l-vsp2.
 * Added vsp1_lookup helper function.
 * Updated comments for LIF0 buffer attribute register
 * Used last ID for rzg2l-vsp2.
RFC->v1:
 * Added reset support as separate patch
 * Moved rstc just after the bus_master field in struct vsp1_device
 * Used data pointer containing info structure to retrieve version information
 * Updated commit description
 * Changed compatible from vsp2-r9a07g044->vsp2-rzg2l
 * Defined the clocks
 * Clock max Items is based on SoC Compatible string

Hi All,

Gentle ping. Are we happy with this patch set?
Please let me know.

Cheers,
Biju
